Closed seams, lateral seams and shaft edges are compressed efficiently and gentle
for material by means of ultra sonic.
The advantage compared with conventional thermal presses lies in the quicker
temperature rise.
E.g. during pressing of turned shoe upper edges the thermoplastic cement is
reactivated and thus a much better result is achieved.
Further advantage is that energy is supplied only during the working process.
Material is fed over a conveyer roller and can be adjusted continuously.
